PAINT.

Specification of Letters Patent.

Patented Nov. 21., 119116.

No Drawing. Original application filed November 19, 1912, Serial No. 732,195. Divided and this application filed May 7, 1915.

i '1 '0 all whom it may concern Be it known that we, AUeUs'rE J. Rossr and CHRISTIAN M. EDWARD SCHROEDER, both citizens'of the United States, and residents, respectively,.of Niagara Falls, in the county of Niagara and State of New York, and of -Rutherford, in the county of Bergen and such as white lead or zinc oxid ground togethcr with such vehicle as the well known drying oils, as for instance linseed oil, and applied in the usual manner by brushing or the like to the surface treated, and our present application for patent is a division of our pending application Serial Number' 732,195, filed November 19,1912.

The objects of our invention comprise the improvement of such paints in their covering or hiding qualities, their durability,

resistance to the weather, and to destructive or dlscolorlng agents present, for mstance,

as in foul air, or in vapors charged with hydrogen sulfid, etc., and also to produce paints having these improved qualities, at less cost than the best paints heretofore manufactured.

1 We have discovered that titanic oxid, as such, now procurable. in quantity as an amorphous powdered product containing a high percentage, say from 96% to 99% of chemically uncombined TiO said powder being white when of highest purity, or slightly yellowish or buff in shade in proportion to the presence, if any, of minute quantities of iron oxid uncombined with said TiO,, is, owing to the peculiar properties of such TiO capable of attaining our said objects when, in production of'paint, substituted, in whole or in part, for the heretoforeemployed pigments, as, for example, white lead or zinc oxid.

To produce our novel pa1nt, we proceed as heretofore practised in the preparation of any desired paint, excepting that, in lieu of the pigment formerly therein employed,

Serial No. 26,504.

we substitute, altogether, or to such extent as desired, a quantity. of titanic oxidin finely powdered state, being, for example, that contained in the amorphous powder above referred to. v Further description is, we believe, unnecessary to enable those skilled in the art to produce our said paints, since it follows that our titanic oxid'pigment is mixed, or also ground, with a drying oil such as linseed oil,

or other suitable vehicle such as dissolved tanic oxid is substituted for said hitherto employed pigments, the ideal embodiment of our invention being a paint the entire pigment of which is such titanic oxid.

Among the numerous advantages and superior qualities attributable to our said novel paint we note that it is uninjurious to animal life in proportion to its content of harmless titanic oxid as compared to poison ouswhite lead or zinc oxid; also that it has superior covering power as compared with that of any other paints known to us; also that it has superior resistance to agencies tending to'discolor and deteriorate previously employed paints, this being, we believe, attributable to 'the comparative stability of titanic oxid; and also that it is more economical of production at the present'cost of titanic oxid compared withwhite lead or oxid of zinc.

We are aware that, prior to our invention, the incorporation into pigments of titanic oxid in crystalline form, or in chemical combination with other substances, has been suggested, the which we do not claim as our in-v vention which consists broadly in our discovery thatonly in its amorphous form and chemically" uncolnbined with other substances can titanic oxid in paints produce the best, if indeed any satisfactory results.

Having now described our invention, What I we claim as new and desire to secure by Letters Patent is the following, viz:

1. Paint containing zinc o-xid and also another pigment containing amorphous titanic oxid (TiO uncombined chemically with.

taining some 1ron oXid and more amorphous titanic oxid (TiO uncombined chemically with other substances. I

3. Paint containing oxid of zinc, and also -a slightly yellowish or bufl' pigment which contains iron oXid and not less than'96% of amorphous titanic oxid (TiO uncombined chemically with other substances.

.4. Paint containing oxid of zinc, and amorphous titanic oxid (TiO uncombined chemically with other substances.

5. Paint containing'oxid of zinc,iron oXid, and also amorphous titanic oxid (TiO uncombinedchemically with other substances.

6. Paint containing zinc oxid and more titanic oxid (TiO uncombined chemically with other substances.
